Specification forming part of Letters Patent No. 122,226, dated December 26, 1871.

Specification describing an Improved Dumping-Car or Truck, invented by FRANKLIN B. CoL- TON, of Philadelphia, Pennsylvania.

My invention consists of a car or truck for transporting and discharging coal, earth, or other material, the said car having a body consisting of two sections adapted to each other and hung to the frame substantially in the manner described hereafter, so that the two sections on being unlocked will be self-separating and discharge their load, and be self-closing after the discharge. My invention consists of further improvements whereby the sections are made selflocking on meeting, may be retarded on tilting,

, and can have their journals and bearings adjusted as circumstances may require, all of which improvements are too fully explained hereafter to need preliminary description.

In the accompanying drawing, Figure l is a side view of my improved dumping-car; Fig. 2, a plan view; Fig. 3, a vertical section on the line 1 2, Fig. l; Fig. 4, a side view of the car, illustrating a braking device attached to the same; Fig. 6, an enlarged view of part of my invention; and Fig. 7, a view illustrating a modification.

Each side frame ofthe car consists, in the present instance, of a longitudinal beam, A, short vertical pieces B B', andupper longitudinal beam D, the whole being properly secured together by any suitable system of bolts and stays. The opposite frames are connected together at their ends by transverse beams a a, and the whole is supported on axles provided with the usual hanged wheels. The body of the car consists of two sections G and G', of the shape, or approximating to the shape, illustrated in the drawing, the two sections, when closed, meeting at the central line w, Fig. l. To each side of each section is secured a journal, b, the centers of two journals of each section being in the same line y, Fig. 2, which is at right angles to a line, w w, drawn through the center of the car, as shown in the plan view,- Fig. 2, and, the journals are adapted to suitable bearings d secured to the beams D D of the opposite side frames. The journals of the two sections are situated at equal distances from the central line x, Fig. 1, this distance, as well as the distance of the journals from the upper edge e of the sections, being substantially that illustrated in the drawing, so that when the body of the car is empty the two sections will, by their own gravity, be` self-closin to each other, and, when loaded, will have tendency to separate and turn in the bearing and assume the position shown by dotted line in Fig. l. In orderto lock the two sections t( gether I prefer the device which I will proceed t describe. On each side of each section is aprt jection, f, the two projections on each side of th car-body meeting and forming together a wedge shaped block, the lower end of which is adapte to a recess, h, in an arm, H, secured to a pin, i arranged to turn in a bearing, j, attached to th frame; a lever, I, being secured to the saine pir There is a similar locking device on each side o the car-body, and the two levers I of the two de vices are connected together by a cross-bar, Z and the weight of the levers and cross-b ar wil suftlce to retain the arm H in an elevated posi tion, although it may be prudent to apply fui ther devices for controlling the arms I, and there by preventing the accidental unlocking of thi sectionsor the tampering of unauthorized par ties with the same.

It will be observed that when the body of th car is loaded and the sections locked together the said body is fastened to the'frame on eacl side at three points, namely: through the mediun of two journals and their bearings and througl that ot' the locking-arm H. 0n elevating thi levers I I the arms H will be depressed and thi projections ff freed from the control of the arms in `other words the two sections of the body wil be unlocked, and, owing to the weight of thi load, will at once turn in their bearings to thi position shown by dotted lines, and the load wil be discharged; Immediately after this dischargf of the load, however, the two sections will, owl ing to their own gravity and the manner in whicl they are hung,` return to their former position in doing which the projections f f will strike th( inclined planes m m of the arms H (See Fig. 6 and depress the said arms until thetwo sections of the body meet, when on the projections f f co incidin g with the recess h of the arms H, the lat ter will be elevated by the weight of the levers II I and the two Vsections will be locked togethei as before. It will be thus seen that the sections of the loaded body are self-separating when unlocked and self-closing and self-locking after the load is discharged. One section must necessarily overlap the other at the top when tilted 5v thus,

Fig. 4, G and Gr show the upper edges of the o sections where they overlap. The end p of e of the overlapping portions of one of the secns is bent so as to bear against the other and us scrape away any dirt which might tend t0 ter between the overlapping portions of the ctions and interfere with their free movement. The upper adjacent corners of the two sections ould slightly overlap, even when the sections e closed. In some cases it may be necessary retard the tilting movement of the sections ter they are unlocked to prevent them from quirin g too much momentum. For this purpose yadopt a braking device, such for instance as is own in Fig. 5. On the journal or trunnion of ych section I place a disk, q, and between them range a rubber, M, controlled by a lever, N, in manner which will be readily understood by ference to the drawing, the brake being applied the peripheries of the disks q q when it is' derable to retard the movement of the sections on .e latter being unlocked. Other braking deces will readily suggest themselves to those miliar with the construction of machinery of .is class. The proper position of the journals trunnions onV the sections is an important atter, as on this will depend the proper funcans of the sections-that is, the self-separating 'the same when loaded, and self-closing when npty;`as the drawing is made in accordance ith the scale below, Fig. 1, this scale will afford le means of determining the position of the urnals approximately, but the exact position of le journals will, in a great measure, depend up# 1 the material with which the sections are loadl some material, forinstance, cannot be sc readv disposed of in tilting the sections as others. hen the load is easily disposed of, the journals ione section may be nearer to those of the oth than when the load is of a character which snders it more diflicult torbe discharged. In l cases, however, the position of the journals iould be such that whenv the loaded sections re unlocked they should acquire such momentum iat they will not begin to close until theload is fully discharged. In order that this end may be always attained I prefer t0 make the journals adjustable on the sections, the bearings being also adjustable on the frameof the car. One way of accomplishing this is illustrated in Fig. 7, vwhere P represents a socket firmly secured to a section, this socket having two ribs toothed on the inside and adapted to a toothed block, Q, which forms partot' the journal, so that the latter can be withdrawn and reinserted in the socket at various distances from the central line av where thetwo sections meet. The bearing d in Fig. 7 is also adjustable, being arranged to slide on a plate, t, attached tothe side Vframe of the car. Many other plans of rendering the journals of the sections adjustable will readily suggest themselves. v

As to the precise shape of the sections, that too,- will, in a manner, depend upon the character of the material with which they are loaded. I prefer the shape shown in the drawing as in my opinion the best for the purpose.

I claim as my invention- 1. A car or truck, the body of which consists of two sections, G G', adapted to each other and hung to the frame of the car, substantially in the manner and for the purpose described.

2. The said sections. hung to the frame of a car or truck, in combination with the locking and releasing device herein described, or its equivalent.

3. Thecombination of the said sections with a braking device for retardin g their tilting movement. Y

4. The said sections having adjustable journals or trunnions, in combination withadjustable bearings on the frame of the car or truck.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

FRANKLIN B. COLTON.
